My fetish for wookiee sex

I like to have sex dressed as Chewbacca. I first discovered my fetish after a Star Wars convention when I went down on a pygmy Leia dressed as the famous wookiee.

Since then I've tried to have Chewy sex as much as possible by frequenting fetish bars and prowling for people on the internet.

However now I've fallen in love and am ready to settle down. My girlfriend is called Debbie and she is lovely. I hope to one day marry her. I certainly don't want to be unfaithful but I just don't think I can give up wookiee sex.

Debbie is quite conventional and comes from a very right-wing family. Do you think she could ever share my fetish? And if so, how do I bring it up?
